Disappointment Peak is a 13,917-foot Sierra Nevada summit in the Palisades area on the boundary of Kings Canyon National Park and the John Muir Wilderness. Rising steeply above the Palisades Lakes, it drains toward both Big Pine Creek and Palisade Creek. Its name originated on July 20, 1919, when J. M. Davies, A. L. Jordan, and H. H. Bliss climbed the mountain thinking they had reached Middle Palisade, then realized their mistake and named the summit for their disappointment. Later climbing milestones included Norman Clyde’s Northeast Couloir ascent in 1930, a difficult traverse to Middle Palisade in 1939, and the first West Face ascent in 1986.
